Now from the Boston Museum of Science, Scitech Today on NECN.
有線新聞波士頓消息。
Well, you may have heard the myth, but do all of those antibacterial products really make bacteria stronger? Joining us now from the Museum of Science, Boston is Dr. Duane Hill. Good to have you here.
我們都聽說過關于抗菌產品的傳說，抗菌產品真的只是會使細菌進化得更加強大嗎？來自波士頓科技館的博士Duane Hill將向我們做詳細介紹。你好。
Oh good morning. How are you?
觀眾們上午好，主持人你好。
I'm good. So are we talking about, you know, what you spray on your kitchen counter and wipe up?
你好。我們需要談論的是噴灑在廚房臺面然后再擦掉的消毒劑嗎？
Sort of, I mean, a lot of those common household disinfectants, ur, that we think of things like Lysol or even things like wet wipes, things like that, have disinfectants in them. There's one research. There's one piece of research that was on in Ireland not too long ago, looked at a common disinfectant called benzalkonium chloride which is the disinfectant that we find in wet wipes, things like Lysol and a lot of those products, even cosmetics that we use everyday.
某種程度上說，是的。我是說一般的家用除菌用品比如煤酚皂溶液，濕紙巾這類用品都含有消毒劑。有一項研究，也就是不久前愛爾蘭的一項研究顯示在濕紙巾，煤酚皂溶液這類產品，甚至是每天都可能用到的化妝品中存在一種名叫氯化苯甲烴銨的物質。
Ok,and the findings are interesting.It was actually making the bacteria grow stronger.
好的，這項研究結果很有趣，因為這些物質可以促進細菌的生長。
Exactly. What they did was they exposed these bacteria, a kind of bacterium called Pseudomonas, it causes a lot of different health conditions in humans. They exposed these bacteria to this benzalkonium chloride, this just infecting for only about a month. And what they found was that the bacteria became not only more resistant to the disinfectant itself but also to the antibiotic Sypro. So the bacteria kind of got a two for one learning by being exposed to this common disinfectant.
沒錯，研究人員找到一種名為假單胞菌的細菌，一種能引起人類疾病的細菌。研究人員將這種細菌與氯化苯甲烴銨相互接觸。僅僅一個月的時間，研究人員發現這些細菌的抗藥性就增強了，甚至能對抗抗生素。因此，暴露在抗菌藥物下，細菌反而生長得更加旺盛。
And why does that happen?
那么，為什么會這樣呢？
Well, I mean, when you think about it, a lot of the things that we have at our disposal, disinfectants, antibiotics are poisons from the point of view of the bacteria. And bacteria have these little things calls efflux pumps. Just little pumps that the cells use, we actually use them ourselves, different ones to pump poisons out of their cells. And what they think was happening is that the bacteria that could figure out how to defend themselves against this disinfectant also use those same pumps to protect themselves against the antibiotic sypro.
當我們想要對付細菌的時候，有很多選擇。消毒劑，抗生素都是細菌的天敵。細菌細胞有一種叫做外排泵的功能，和我們人類的基本相同，都是將有毒物質排出機體的功能。正如人體細胞，細菌細胞同樣能對抗抗細菌產品甚至是抗生素，把它們排出體外以保護自己。
Does that mean you should throw away your little wet wipes?
這是說我們要扔點濕紙巾這些產品嗎？
Absolutely not. No one is saying that we should stop using disinfectants. Disinfectants are really important part of our arsenal against bacteria. But I think what the research is suggesting is that physicians, public health professionals, we ourselves need to kinda think about what some of the side-effects might be from these disinfectants and not just grab them and use them so indiscriminately. We need to kind of think about it.
當然不是，沒有人說我們不能夠實用抗細菌產品。抗細菌產品是我們對抗細菌的有效武器。但我認為這項研究想要做的是提示醫生們，以及所有的衛生行業從業者們，我們不能不加選擇地一味使用抗菌產品而忽視它的副作用，我們應當適當地考慮一下。
Woo it's interesting, Dr. Duane Hill, thank you so much for joining us this morning.
很有趣，Duane Hill博士，謝謝你的介紹。
Oh, my pleasure!
不客氣！
